Detection of Missing Value in Deck

The stunt of detecting with only a riffle through the pack the absence of four cards of the same value is Joe Berg's “Super Detection”, first published in The Sphinx, Vol. 28 No. 1, Mar. 1929, p. 25, under the title “A First Sight Card Trick”, and then in Berg's Here's Magic, 1930, p. 16. The mention in a letter from Jay Marshall of it being performed by Morris “Moe” Seidenstein when Marshall was “a kid” (probably the 1930s) has led at times to it being mistakenly believed to be Seidenstein's idea (see Moe and His Miracles with Cards by William Miesel, 1986, p. 51).
